SFSC Heat Removal System 3.1.2 Certificate of Compliance No. 1014 Amendment No. 15 Appendix A 3.1.2-1 3.1 SFSC INTEGRITY 3.1.1 Multi-Purpose Canister (MPC)
LCO 3.1.1 The MPC shall be dry and helium filled.
Table 3-1 provides decay heat and burnup limits for forced helium dehydration (FHD) and vacuum drying. FHD is not subject to time limits. Vacuum drying of MPCs may be subject to time limits, from the end of bulk water removal until the start of helium backfill, as shown in Table 3-1.
APPLICABILITY: During TRANSPORT OPERATIONS and STORAGE OPERATIONS.
ACTIONS
NOTES---------------------------------------------------------
- 1.
Separate Condition entry is allowed for each MPC.
- 2.
MPC helium leak rate limit for cover plate base metal listed in Condition D and SR 3.1.1.3, is not applicable to casks that were loaded to Amendments 2 through
- 7.
CONDITION REQUIRED ACTION COMPLETION TIME A.
MPC cavity vacuum drying pressure or demoisturizer exit gas temperature limit not met.
A.1 Perform an engineering evaluation to determine the quantity of moisture left in the MPC.
7 days AND A.2 Develop and initiate corrective actions necessary to return the MPC to compliance with Table 3-1.
30 days
Programs 5.0 Certificate of Compliance No. 1014 Amendment No. 15 Appendix A 5.0-8 ADMINISTRATIVE CONTROLS AND PROGRAMS 5.8 Fabrication Helium Leak Test At completion of welding the MPC shell to baseplate, an MPC confinement weld helium leak test shall be performed using a helium mass spectrometer. This test shall include the base metals of the MPC shell and baseplate. A helium leak test shall also be performed on the base metal of the fabricated MPC lid. The confinement boundary leakage rate tests shall be performed in accordance with ANSI N14.5 to leaktight criteria. If a leakage rate exceeding the acceptance criteria is detected, then the area of leakage shall be determined and the area repaired per ASME Code Section III, Subsection NB requirements. Re-testing shall be performed until the leakage rate acceptance criterion is met.
Casks initially loaded to Amendments No. 2 through 7 must meet the following:
- Casks fabricated on or after July 1, 2009 a fabrication helium leak test at completion of the welding of the MPC shell to baseplate must be performed in accordance with the above requirements.
- Casks loaded before July 1, 2009 must meet the fabrication helium leak test requirements of the lid base metal of the amendment to which they were originally loaded.
